Sgminer HW errors please help

[reg008]

Hi all,
Broke my head setting up Darkcoin mining on 2x7950 rig.
Tried different core/mem clocks hashrate is fine (up to 1600 mh per card) but still not a single accepted share - HW errors only

My config:

{
"pools" : [
],
"kernel" : "darkcoin",
"gpu-threads" : "2",
"worksize" : "256",
"lookup-gap" : "2",
"shaders" : "1792"
}

also tried variety of thread-concurrency and intensity values

"thread-concurrency" : "8192",
"intensity": 13

Any thoughts on what's wrong ?

Thanks !

Thread concurrency and shaders together are useless, just use one of them.
Try to lower clock and memory speed and check if anything changes

Tried that with no change at all.
Not a single accepted share.

Bro i think your driver version cousing this... same happened to me!

what driver version do you have

alo try remove shader options from conf.

1 - exactly what version miner are you using?
2 - OS, driver version
3 - card brand?
4 - full config file please !! (hide personal info if you're paranoid)

try only 1 gpu thread, and work 128 (one at at time). I know it sounds nuts, but my x11 config is completely different to my scrypt config. I'm using intensity 19 for MPOS and 18 for p2pool for example. This is insane under scrypt.

Catalyst 13.1 Windows 7 64bit
My config is in my first post.
Thanks for help it seems that my Catalyst driver is slightly outdated !

I believe windows prefers Catalyst 12, but if it was working fine before, its not the drivers.

Take a read here, may help, good luck!
